I don't think it would be odd at all!
Christian is used in a variety of languages and
Frederik is close enough to
Frederick that I don't think it would be too far fetched for you to use it, especially as a middle name.
As for the little Danish prince, I'm placing a bet on the names
Christian Joachim Waldemar/Valdemar
Henrik.
